DriveNow goes electric: BMW is using the i3 in its carsharing system. The Morgan Three-Wheeler, a vintage English eccentric on three wheels. And powerful and proud: the Bentley Continental GT3 on the Nürburgring race track.Examine it! BMW Drive NowWhere others paved the way, BMW is now following suit. Electric cars will now be available as part of DriveNow's car sharing range -- and not just any cars. BMW is releasing 100 of their innovative i3 models in three German cities. Over the past two years in Berlin, DriveNow has put forty electric 1-series BMWs into service.Vintage: The Morgan Three-WheelerBetween 1909 and 1953, some 30,000 Morgan Three-Wheelers were built in Malvern, England. Morgan's reasons for building them were not so much technical as economic. The tax on four-wheeled vehicles was higher at that time. But owners had the option of registering the three-wheelers as motorcycles at a much lower tax rate. That made the car far more affordable for young families.Admire it!: The Bentley Continental GT3 - Blancpain GT SeriesBritain's luxury make Bentley has a long racing tradition. Walter Owen Bentley founded the company in 1919. He was a passionate racer and drove home several victories. The tradition is being carried on by the latest Bentley Continental GT3 racer in the Blancpain Endurance, the world's biggest GT-3 racing series. Drive it! was on hand at the Nürburgring track.Taste it!: The Mini 5-Door HatchPerky, modern... yet timeless. The Mini has been a mainstay in the sporty subcompact segment for decades. It looks almost like someone had taken the 3-door version and stretched it out till it was long enough for two more doors. We took Mini's 5-door hatch out for a test drive to see if it had sacrificed any of the top-notch comfort and handling familiar from the 3-door version.Vintage: The Porsche 911 TargaMany consider the Porsche 911 is considered to be THE sports car par excellence. The first open-top 911 was the Targa with its characteristic roll bar. The brainchild of company chairman Ferry Porsche and his son Ferdinand Alexander Porsche, who designed the 911, the roll bar was made to protect the convertible's inhabitants in case the car flipped over.In 1965, its appearance drew mixed reactions. Still, over a quarter of the 911s purchased at the time were Targas.

The Spyder is the lightest and simultaneously the most powerful car in the Boxster series. It's a convertible that combines purism and power. Its lightweight roof and low driver position make for a low center of gravity. That and the 'streamliner' humps behind the roll bars give the vehicle its characteristic look.The car is powered by the 3.8-liter, 6-cylinder, 276-kilowatt engine familiar from the 911 Carrera S and has a 6-speed manual transmission. The Spyder accelerates from zero to 100 in 4.5 seconds and reaches a top speed of 290 kilometers an hour.

The Frankfurt Motor Show presents mobility in an era of change. Electric vehicles could soon park themselves and charge their own batteries. But in a Porsche Boxster Spyder, you'll want to do everything yourself!Examine it!

Taste it! Mazda 2The new Mazda 2, also badged as the Mazda Demio, has shed its conservative image. The supermini's new look is sleeker and sportier. Mazda is targeting its M2 at younger, image-conscious buyers looking to make a self-confident appearance. And here the Japanese model definitely delivers.Its striking radiator grille and sharp headlights are similar to those used in the Mazda 3 and Mazda 6, and have already received a warm reception. We put the 66 kilowatt, gas-powered M2 through its paces.

Picture it! VW V-Charge - Automatic Parking and ChargingThe driver simply drops off a car at a parking garage and goes shopping or straight to an appointment, while the vehicle locates a parking spot all by itself. And more than that: if the garage has charging stations, the car can even hook itself up, recharge its batteries and then park itself afterward, making the station available to other cars - all automatically.Self-parking cars pose no danger to other drivers or pedestrians: cameras, ultrasound sensors and emergency braking systems already developed for conventional models have been adapted for use in the V-Charge project. We look at the self-charging car and the charging station with its robot arm at work.

Vintage! Tatra T87It looked like something from a 1930s science fiction series: the 1937 Tatra T87 was the avant garde of automotive design. Even with an output of just 75 horsepower, the aerodynamic T87 still reached tops speeds close to 150 kilometers per hour. Spats over the rear wheels and the long, sloping rear were an early attempt at streamlining.The striking fin down the back helped to stabilize the car at high speeds. Tatra collector Ulrich Platzek found his personal T87 not far from the old Tatra plant in the Czech Republic. Drive it! takes a closer look at this fanciful vintage Tatra.
